Re: st: How to re-program -save9- for Stata 13?

[Sergiy Radyakin <serjradyakin@gmail.com>]

Stas,

Stata 8 and 9 share the same data format (specification 113), so
although SPSS says it writes in 5-8, it should equally read and write
9 (perhaps the menu text was designed at the time Stata 9 did not
exist yet). Here is another reference it supports 9:
http://www.ats.ucla.edu/stat/mult_pkg/faq/fromStata_toSPSS.htm

But introduction of reading Stata dataset capability was apparently
added in version 14 (contrary to the above reference):
http://pic.dhe.ibm.com/infocenter/spssstat/v20r0m0/index.jsp?topic=%2Fcom.ibm.spss.statistics.help%2Fwhatsnew_14.0.htm

Furthermore, it seems the request for support of newer Stata formats
was requested still in the 17th generation of SPSS:
